To all whom it may concern:

Be it known that I, CLARENCE J. LAWSGN, a. citizen of the United States, residing at Yonkers, Westchester county, New York, have invented a new and useful Improvement in Machines for Making Bottle-Caps, of which the following is a specification.

My invention relates'to machines for assembling and uniting the metal shells and sealing gaskets or cork dlsks with adhesive material, which caps are commonly used for sealing bottles and my ob e cts are the construction of a machine in wh1ch no heat will be employed in the structure ltself, 1n which the caps will not be subJected to continued pressure and in which the gaskets or cork disks will not be subjected to in ur1ous temperatures and in which the assemblmg and uniting of the various parts of the caps will be continuous. p

In the drawings Figure 1 is a plan view of the machine; Fig. 2 a side view of the structure of Fig. 1; Fig. 3 a detail view of the adhesive material feeding device. F g. 4 a top view of the structure of F1g. 3:; Fig. 5 a side view of the structure of Fig. 3; and Fig. 6a view showing'the method of final assembly of the cap.

The machine comprises a base 1 with a main shaft 2 extending across it. A pulley 3 serves to drive the machine. Eccentrics 4, 5 and 6 give motion to the connecting rods 7 and 9 and lever 8 as will be hereinafter explained.

A table 10 forms the top of the machine and carries a plate 11 with a ratchet 12 thereon, arranged to rotate on the table. The plate 11 is provided with a plurality of holes 13, the upper parts of which are cut out or flared toward the edge of the disk at 14 as is best shown in Fig. 1. i

A spring pressed button 15 mounted on the table bears on the edge of the disk to prevent overrunning and the rounded head enters the flares 14 to properly position the plate 11.

At one end of the table is placed a slide vhesive material.

The reciprocation is effected by the lever 8 which is fulcrumed at 24 to the base and pivoted to the end of the slide 16 at 25 so that as the eccentric 5 revolves the slide 16 is given a backward and forward movement. As is well understood, this mechanical movement contemplates the employment of a yoke at the lower end of the lever 8 and a slot at the fulcrum.

An arm 19 carries a reel 20 which holds a supply of adhesive in the form of a strip or ribbon of paper 1- saturated with an ad- This paper ribbon is fed across the top of'the gasket slide 16 by a roller 21 which presses it against a second roller 22, the motion being transmitted from one roller to the other by the spur gears 21 and 22.

A die or punch 23 reciprocates to punch out disks of adhesive paper'and lay them on the gaskets beneath. This die is backed off as shown in Figs. 3 and 5 so that the return stroke will not tear the punched out ribbon of paper.

The reciprocation of the die is efi'ected by mounting it on a block 26 which slides in a bracket 27, the block being raised and lowered by the connecting rod 9 as the eccentric 6 is revolved.

A pawl 28 on the feed slide 16 engages the ratchet 12 on the plate 11 and advances the plate a notch (or hole) at each complete reciprocation of the slide block.

A pawl 29 on an arm 30 engages a ratchet 31 on the roller 21 to feed the adhesive paper on each stroke of the punch 23, the upper end of the arm being slotted and engaging a pin 32 on the block 26 so that each time the block 26 rises the rolls are turned through a fixed distance moving up the paper sufliciently to cut a new paper disk.

On the table opposite to the gasket and adhesive placing apparatus is a chute 33 through which tin shells are fed to the machine, being inserted in the flares 14 over the holes 13 as the plate 11 revolves.

A slide block 34 on a support 35 carries a series of plungers 36 each of which extends through a hole in the table in line with the path of the holes 13 in the plate 11 and is compresses the spring 37 and squeezes the members of the assembled cap into complete contact.

A rigid plate 38 above the plungers serves as an anvil against which the caps are driven and squeezed by the lungers 36.

A wiper 39 in the path of t 1e caps beyond the plungers serves to eject them from the machine.

The operation of the machine is as fol- -lows:-The gasket tube bein filled with disks, the reel containing a roll of adhesive paper and the chute being supplied with well heated caps the machine is started. The reciprocation of the gasket slide moves the bottom gasket over a hole in the plate 11, the punch 23 descends and cuts out an adhesive paper disk, the continued downward movement of the punch or die 23 pushing the gasket and paper into a hole in the plate. ()n the up stroke of the die 23 the ratchet and pawl mechanism feeds up fresh adhesive paper so the next paper disk can be punched out and the second stroke of the gasket slide moves the plate 11 up one hole through its ratchet and pawl mechanism so that the next hole is under the punch 23. These operations are continually repeated. When the gasket and aper reac the chute 33 a hot metal shell 1s placed, skirt down, on top of the hole contalning the cork and paper and a plunger 36 rises and drives the gasket, paper and metal shell against the plate. 28 and into intimate contact, the heat of the metal sufliciently softening the adhesive to cause the parts to adhere. The second and third plungers (marked a and 'b on Fig. l) strike the caps successive blows as they stop over them so that the tendency of the gasket to leave the shell is resisted. On reaching the wiper 39 the finished caps are ejected. By this construction and method of operation no heating means are employed in the machine proper and the for supplying sealing -over and cork disks, (generally treated with parafiin) are not subjected to'inj-urious tem eratures. As the machine is not heated arti cial coolm means are unnecessary.

1. In a cap making machine the combination of a table, a plate on the table provided with holes adjacent to its edge, means gaskets and adhesive material to said holes, means for imparting a step by step rotation to said plate, means for supplying metal shells to the gaskets and adhesive at a. given point, and a series of reciprocating series of blows to the assembled caps.

2. In a cap making machine the combination of a table, a plate thereon provided with holes near its edge, a gasket magazine on the table, a feed slide passing under said magazine and over the path of the holes in the plate, aratchet on the plate, a pawl on the feed slide cooperating therewlth and means for reciprocating the slide whereby a step by step rotation will be imparted to the plate.

3. In a cap making machine the combination of a table, a plate thereon provided with holes near its edge, means for imparting a step by step rotation to the plate, means for supplying the holes with askets, adhesive and metal shells, a plura 't of plungers below the plate, a rigid disk t eremeans for reciprocating said plungers whereby the gasket, adhesive and metal shell will be driven into intimate contact between the plungers and rigid plate.

In testimony whereof I have hereunto subscribed my name in the presence of two attesting witnesses.
